The aim of the present study was to investigate the protective role of Ginkgo biloba leaf extract against uranium (U)-induced toxicity in Swiss albino mice. The mice were randomly divided into six groups, each consisting of six animals: Group I (control) received tap water alone, Group II received U at a dose of 5mg/kg of body weight, Group III received G. biloba at a dose of 50mg/kg of body weight, Group IV received G. biloba at a dose of 150mg/kg of body weight, Group V received G. biloba (50mg/kg of body weight) and U (5mg/kg of body weight), and Group VI received G. biloba (150mg/kg of body weight) and U (5mg/kg of body weight) by oral gavage for 5 days. Serum aspartate aminotransferase (AST), alanine aminotransferase (ALT), blood urea nitrogen (BUN), and creatinine levels were determined to assess liver and kidney function, respectively. Also, liver and kidney samples were taken for the determination of tissue malondialdehyde (MDA) and reduced glutathione (GSH) levels, and histopathological changes in liver and kidneys were investigated. The results indicated that there was a significant increase (P

Biological compounds with antioxidant properties may contribute to the protection of cells and tissues against deleterious effects of reactive oxygen species (ROS) and other free radicals induced by cisplatin. This study was performed to investigate the possible protective role of antioxidant treatment with grape seed extract (GSE) on cisplatin-induced testes oxidant injury using biochemical approaches. The degree of protection produced by GSE was evaluated by determining the level of malondialdehyde (MDA) and glutathione (GSH), the activity of catalase (CAT), glutathione peroxidase (GSH-Px), were estimated from testes of rabbits. Male New Zealand white rabbits were divided into 3 groups (n=6):1-Control group(1 ml saline. i.p) 2-Cisplatin group (a single dose of cisplatin (5 mg/kg, i.p) 3- A single dose of cisplatin (5 mg/kg, i.p) + GSE (250 mg/kg/day, i.p) for 6 days. MDA level were significantly higher when compared to Control (p<0.05). In Cisplatin+grapes groups MDA levels were found significantly lower than cisplatin group (p<0.05). GSH levels were decreased with cisplatin compared to control but in case of cisplatin+ GSE it increased (p<0.05). In treated rabbits, the activity of CAT and GSH-Px was decreased in cisplatin and cisplatin+ GSE groups compared to control (p<0.001). These results indicate that the antioxidant GSE might have a protective effect against cisplatin-induced testiculer damage and oxidative stress in rabbit.
